It is common to access regmap registers at bit level, using
regmap_update_bits or regmap_read functions, however the end user has to
take care of a mask or shifting. This becomes overhead when such use

and less error prone.

So this looks basically good.  A couple of smallish nits below, if you
could respin I'll apply this on a branch so it can be pulled in as
dependency for the other things that use it.

Needs a blank line between the two functions.

Probably not worth inlining these, just put them in the code.
